Heat input dikendalikan melalui variasi tekanan gesek sebesar 14 MPa, 19 MPa, dan 24 MPa serta waktu gesek 5 detik, 6 detik, dan 7 detik. Kualitas sambungan dievaluasi melalui pengukuran burn-off length, uji tarik, uji kekerasan, pengamatan struktur mikro, pengukuran ketebalan interface, dan analisis senyawa intermetalik menggunakan X-Ray Diffraction (XRD). Hasil penelitian menunjukkan bahwa peningkatan heat input meningkatkan burn-off length dari 20–23 mm pada tekanan gesek 14 MPa menjadi 25–28 mm pada tekanan gesek 19 MPa dan mencapai 29–32 mm pada tekanan gesek 24 MPa, yang menunjukkan bertambahnya energi panas dan deformasi plastis selama pengelasan. Kekuatan tarik tertinggi diperoleh pada parameter 24 MPa dan 5 detik sebesar 118 MPa dengan ketebalan interface sebesar 2,88 µm, yang menandakan terbentuknya ikatan metalurgi yang padat. Sebaliknya, pada parameter 24 MPa dan 6 detik terjadi peningkatan ketebalan interface hingga 12,93 µm yang menyebabkan penurunan kekuatan tarik menjadi 89 MPa akibat terbentuknya lapisan senyawa intermetalik yang bersifat getas. Uji kekerasan menunjukkan peningkatan nilai kekerasan pada daerah interface hingga 84,9 HV, sedangkan pengamatan struktur mikro memperlihatkan perluasan zona TMAZ dan peningkatan deformasi plastis seiring meningkatnya heat input. Analisis XRD mengonfirmasi keberadaan senyawa intermetalik AlCu₄, terutama pada parameter dengan temperatur tertinggi sebesar 212 °C. Penelitian ini menyimpulkan bahwa heat input optimum dicapai pada kombinasi tekanan gesek 24 MPa dan waktu gesek 5 detik.
